Each shaft has its outer end portion 45 ers or wheels I2 adapted to engage a lower rail, welded, as at I9, to a plate 20. The shafts pass, as on a supporting structure, and to be engaged desirably snugly, through openings 2| in the by an upper rail,'as on a revolvable platform. outer band II, and the plates 2!] are secured to The rollers or wheels I2 are freely rotatable said outer band by headed and nutted bolts 22, on shafts I3 mounted in said inner and outer one at either side ofeach shaft. The bolts 22 bands I0 and II, in a 'manner .to be described, pass through the plates 20 and the band II, and at equally spaced distances apart about the full the headsand nuts on the bolts clamp said plates circumference of the container ring. 20 against the outer surface of the outer band. Each of the bands I0 and II could consist: of The'plates 2 0 are arcuate in the direction of their 5519, single circular strip or piece of metal. As lengths to lit the outer band. A washer 23 is situated upon each shaft I3 between the inner surface of the outer band and the corresponding roller or wheel I2. Each shaft 13 includes a reduced threaded portion 24 at the inner end of the shaft which passes through the inner band and provides a circumferential shoulder 25 adjacent the interior or outer surface of said inner band. A nut 26 upon each threaded portion 24 is turned home against the exterior or inner surface of the inner band, to force said band against the corresponding shoulder 25. The rollers or wheels 12 are desirably of width to about span the distance between the inner band In and the washers 23.

The container ring supports the rollers or wheels l2 in a circumference having diameter equal to that of the circumference described by upper and lower rails in connection with which the container ring is to be employed, and the traveling surface of each roller or wheel may be grooved, as indicated at 2'|,to fit upper and lower rails.
